Another important obiect of the present in- Vention is to rovide a handcart havin a ver-- tical v a iustable rear wheel construction, wherebthe cart mav be moved upwardly over Curbs of various hei hts,

A further ohiect of the present invention is to provi e a h n cart ofthe aforementioned character invol n a nov l nd impro ed rear wheel mounn that is cuicklv and r a ilv a ustable to selectiveiv rai e and lowerthe w eels of the mount lat v to th front wh els of the cart.

A still further aim of the present nvention is to vide a han cart th tis s m an pract cal in construct on. stron and. reliab e in use, all ancomp ct n structu e. inexn 'o ve to manu act e. an othe wise well a edfor the pur es for which the same is intended.

Other obiects and advanta es reside in the details of construction andoperation as more fully hereinafter described and claimed. referencehm'n had to the accompany n draw n s forming part hereof. here n likenumerals refer to l ke parts throu hout. and in which:

Fi ure l is a fra mentary side elevational view of the invention aboutto he moved over a curb:

F ure 2 is a perspective view of the present in nt on: and

Fi ure 3 is a rear view of Fi ure 2.

Referrin now to the raw n s in detail, wherein for the purpose ofillustration. there is disclosed a preferred embodiment of the presentinvention, the numeral in represents a frame inclu na a U-sha'oedtubular member l2 whose leg portions are jo ned by cross-straps Hi. Theends of the c oss-straps are fixed by wel ing or the like to the legport ons of the member 2 and the central ortions of the cross-straps l4are fixed by welding or the like to a central longitudinal strap l6whose upper end supports a laterally proiecting hand grip l8.

A ledge forming member 20 is fixed to the ends of member l2 to retainarticles on the frame Ill. The member 20 is formed with rearwardly andupwardly inclined brace and support arms 22 that are fixed to a frontaxle 24 carrying wheels 26. The axle 24 is further supported and bracedto the frame It by downwardly and rearwardly inclined arms 28.

A pair of anchor elements or plates 30 are fixed by welding or the liketo each of the arms 28 and include rearwardly projecting cars 32 thatare secured to the forward ends of links or pitmans 34 by pivots 36. Therear ends of the links 34 support the ends of a rear pair of axles 38each of which carries a wheel 40.

A channel member 42 is fixed to the strap l6, medially the ends of thestrap l6, and its flanges are provided with longitudinally spacedapertures 44 with the apertures in one flange registering with theapertures in the other flange.

The furcations of the bifurcated end 46 of a connecting member 41 eachsupport an axle 38. The axles 38 are coaxial with respect to each otherand their inner ends are fixed by welding or the like to the furcations.The furcations are spaced apart sufiiciently to accommodate the leg ofan operator especially during adjustment of the device. The other end ofthe member 41 is formed with an aperture for selectively registeringwith the apertures 44. A fastener 50 extends through the aperture inmember 41 and the apertures 44 in registry with the aperture in member4'! to permit raising or lowering of the wheels 40 in accordance withthe height of the curb over which the cart is to be moved.

In practical use of the invention, the wheels 40 are disposed over thecurb to be employed as fulcrums to raise the lower end of the frame andthe wheels 26 over the curb as shown in Figure 1.

Having described the claimed as new is:

1. A hand cart comprising a frame, a front axle supported on the frame,brace means between the axle and the frame, a rear pair of coaxialaxles, anchor elements fixed on the brace means, links terminallypivotally connected to said elements and to said rear axles, a channelfixed to the frame perpendicular to the axles, a connecting memberhaving a bifurcated end carried by the rear axles and a straight portionadjustably secured to the channel, a rear wheel on each rear axle andforward wheels on the front axle.

2. A hand cart comprising a frame, a front axle supported on the frame,brace means between the axle and the frame, a rear pair of coaxialaxles, anchor elements fixed on the brace means, links connecting saidelements to said rear axles, a channel fixed to the frame perpendicularto the front and rear axles, said channel including spaced flangeshaving longitudinally spaced apertures therein with the apertures in oneflange being in registry with the apertures in the other flange, aconnecting member having a bifurcated end pivoted on the rear axles,fastening means carried by the other end of said connecting member andselectively received in said apertures, front wheels on the front axle,and a rear Wheel on each of the rear axles.
